MACHINE FOR MAKING SEAMLESS STOPPEFIS- SPECIFICATION forming part of Letters Patent No. 771,421, dated October 4, 1904. Application filed November 16, 1903. Serial No. 181,389. (No model.)

To'rtll whom, it may concern.-

Be it known that I, EMIL ERNEST DEMELY, a citizen of the United States, residing at Westvport, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Machines for Making Seamless Stoppers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to a machine for forming seamless bottle-stoppers or similar articles of glass or the like.

The object of my invention is to provide a machine of this character which will be simple and comparatively inexpensive in construction, durable in use, and very eflicient in operation.

With this and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure lis a front elevation of a machine embodying my invention. Fig. 2 is a side elevation of the rotating head, showing the same removed from the table or support of the machine. Fig. 3 is a vertical central sectional View through the same and a portion of the support, showing the forming-jaws separated. Fig. 4 is a top plan view of the rotating head. Figs. 5 and 6 are horizontal sectional views taken, respectively, on the lines 5 5 and 6 6 of Fig. 2. Fig. 7 is a detail view of a modified form of my invention.

In the embodiment of my invention as illustrated in the drawings the numeral 1 denotes a suitable support or table of any desired construction, upon which a rotating head 2 is mounted. Said rotating head comprises a central hollow or tubular shaft 3, to the lower end of which is secured an attaching-plate 4 and to its upper end a guide-plate 5. Pivoted at their lower ends, as at 6, between ears or lugs 7 formed on the attaching-plate 4. at equidistant points from each other and from the center shaft 3, are three carrying-arms 8,

disposed vertically and having their upper ends projecting through radially disposed slots 9 in the guide-plate 5, which guide them in their swinging movement toward and from each other and the center line or axis of the head. Said arms 8 are provided at their upper ends above the guide-plate 5 with forming-jaws 10, the inner faces 11 of which are of the contour it is desired to have the bottlestopper or other article to be made by the machine. The inner faces of the formingjaws immediately below the forming or shaping faces 11 are beveled, as clearly shown at 12 in Fig. 5, to cause said jaws to aline concentrically when in their closed position. As previously stated, the faces of the forming-jaws may be of any desired shape; but when the stopper or other article is to have a flat top or end the said flat end is preferably formed upon the top of the guide-plate 5, as clearly shown in Fig. 7 of the drawings. Secured upon the upper ends of the jaws 10 by screws or other fastening means 13 are cutters 14 in the form of circular disks, the cutting edges of which are adapted to partially sever the stopper or other article being formed from the mass of material of which it is made. In order to actuate said arms 8 and the formingjaws 10, which they carry, an operating-rod 15 is slidably disposed within the hollow center shaft 3 of the rotating head. The upper end of said rod 15 is attached by means of a cross-pin 16, which projects through longitudinally-disposed slots 17 in said hollow shaft, to a sleeve 18, slidably mounted on the shaft 3 between the plates 4 and 5. Said sleeve is formed with three ears 19, to which one end of each of three toggle-levers 20 is pivoted. The opposite ends of the toggle-levers are pivotally connected to the inner end of pins 21, which project through apertures or openings in the arms 8. Said pins are formed with shoulders 22 by reducing the portions which project through the arms, and said shoulders are held against the inner faces of the arms by fiat springs 23, one end of each of which is adjustably attached to the outer end of one of the pins 21 by means of nuts 21, and the other end of each of said springs is secured upon the outer face of one of the arms 8, as

shown. that the arms will be permitted to have an outward-swinging movement independent of that which they receive from the toggle-levers when the operating-rod 15 is elevated.

In order to hold the arms 8 in their closed ornorma'l position, a coil-spring 24 is confined on the lower portion of the operatingrod between the under side of the attachingplate 4 and a fixed collar 25. Said spring 24 exerts its energy to force the rod 15 downwardly and draw the toggle-levers inwardly, the springs 23 holding the arms against the shoulders of the pins carried by the togglelevers, as previously described.

The head 2 may be rotatably mounted in any desired manner; but 1 preferably secure to the under side of the attaching-plate 4 a plate 26, which carries a depending sleeve or tub'ular shaft 27, which is adapted to surround a portion of the lower end of the operating rod 15 and the coil-spring 24. Said plates 4 and 26 are secured together by tie-bolts 28, which pass through apertures in plates 4 and 5', and through slots in the plate 26. These bolts space the plates 4 and 5, and thus strengthen the head 2, as will be readily understood. The sleeve or hollow shaft 27 is revolub'ly mounted the table or support 1 and has attached to it a gear or pinion 29, which meshes with a gear 30, secured upon a vertical shaft 31. Said shaft 31 also carries a beveled gear 32, which meshes with a similar gear 33 upon one end of a horizontal shaft 34. 35 denotes a pitma'nr0d attached to said gear, by Ineansof which it may be rotated from any suitable source of power.

The operating-rod15 may be controlled by either a hand or foot lever. As shown in Fig. 1 of the drawings, a grooved collar 36 is secured to the lower end of said rod and engaged by the forked end of aliand operatinglever 37, which is pivoted at 38 between lugs depending from the under side of the table 1. The handle 39 of said lever projects above the surface of said table and is within convenient reach of the operator of the machine.

In order to hold or support the glass or other material in the machine, a vertical standard or upright 40 is provided upon the table adjacent to the rotating head. Slidably mounted upon said standard is an arm 41, (one or more, as desired,) which is adapted to be adjusted and fastened at any desired elevation by a setscrew 42. The outer endof said arm is formed with a jaw disposed in line with the center of the rotating head and adapted to receive the rod 43, upon the lower end of which is held the glass from which the bottle-stopper is to be made. I

The operation of my invention is as follows: By means of the gearing previously described or by any suitable means the head 2 is rapidly rotated either to the right or left, or, if so desired, alternately in both directions. The

By this construction it will be seen hand-lever is then depressed to force the formingja\vs apart, and the molten glass,,which is gathered on the end of the rod 43'and rolled on a plate or partly shaped, is inserted between the open jaws, the upper end of the rod 43 being then attached to the arm 41, which has been adjusted at the proper elevation. The hand-lever is then gradually released, so that the coil-spring 24 will lower the operating-rod 15 and draw the jaws togcther upon the glass. The rotation of the forming-jaws about the body of rapidly-cooling glass will shape the same, as will be readily understood.

It will be seen that by means of mymachine seamless glass bottle-stoppers, which have formerly been made by hand, may be formed and finished in a simple and inexpensive manner.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the prin' ciple or sacrificing any of the advantages of this invention.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is
